What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Question: What led you to your ideas about consciousness?Daniel Dennett:   I think that, in a certain sense, I’m an engineer monkey.  If I had a slightly different upbringing or slightly different parenting or something, I think I would have been an engineer.  I’m fascinated with how things work, taking things apart, putting them back together again. So for as long as I can remember, I’ve been puzzling about how consciousness could work. What can be going on in between one’s ears that could explain all of the things that happen?

And what fascinated me, over the years, was that people had some pretty interesting glimmers.  I think well, there’s got to be something right about this bit, and there’s got to be something right about that. So I just began to accumulate those and think about how to put them all together. And of course, I can’t put them all together at any level of detail, but I could sketch out a big picture.  It’s a little bit like what software engineers do when they just work out the specs.  Here are the systems; it can do this, this, and this, and it’s got to be able to do this too.  And they don’t yet know exactly how to build something that has all those competences, but at least they have sketched out what the competences are. 

So I began to make an informal specs list.  This is what consciousness does.  Now, can I imagine ways or can anybody, or has anybody already done it and save me the trouble that consciousness can do this and this? And I think the great power of thinking that way is that it keeps you from just stopping in your tracks, slack jawed and wondering and thinking, “Oh, my gosh! This is just impenetrably fantastically mysterious.”   

I think that’s a very natural attitude. But whenever you feel it you should say, okay, back to work: why is it so wonderful? What does this part of consciousness add to the mix? What does it do? And then what happens? Okay, you had this experience, and then what happens? What can you do because you had that experience that you couldn’t do if you haven’t had that experience? Or what happens in you because you had that experience that wouldn’t happen in you without that experience?

And if you just break the problems down calmly like this. You begin to build up a sense of all the things that need to go on for us to be conscious. 

Now, once you’ve got that list, the mistake is in assuming that after you’ve explained all those, there’s in addition this further part of the hard problem: where does consciousness come in? No that is, that is consciousness.  If conscious isn’t another thing?  It’s all of those tricks.
